New energy technology bottlenecks gradually break through the cost control of non material factors

In the days before the fourth session held China New Energy International Forum, Vice Minister of the Ministry of science and technology Cao Jianlin pointed out that the progress of science and technology of strategic emerging industries have become increasingly prominent, "11th Five-Year" China won many breakthroughs in key technologies in the development of new and renewable energy, a series of industrialization demonstration project started to accelerate the application of new energy technologies and products, but the lack of investment in research and development, cost control and lack of penetration into the social life and other constraints still exist, there are many obstacles in the future technology and industrial development.

The breakthrough of key technology demonstration projects to promote

Cao Jianlin pointed out that in 11th Five-Year China's new energy sector has successfully mastered a number of key technologies with independent intellectual property rights, the development of a number of sets of equipment in line with China's actual or potential technology. In the field of wind power, at present our country has mastered 1 ~ 3MW doubly fed VSCF wind turbine series design technology; 1.5MW direct drive permanent magnet wind power technology has achieved mass production; designed and developed 1.5 ~ 2.0MW wind turbine blade, the domestic machine manufacturers to achieve mass production.

In the field of photovoltaic power generation has been built in Yiwu International Trade City 1.295MWp solar grid power plant the largest scale, and to achieve power generation; completed the design of MW concentrating photovoltaic power plant, in addition to desert photovoltaic power grid more 10MW level is the design of the building. Independently developed with the international advanced level of 250kW and 500kW grid connected photovoltaic power plants, and the realization of the space operation.

According to reports, in response to the financial crisis, the Ministry of science and technology, the Ministry of Finance jointly launched a series of industrial demonstration projects. Such as the "Ten City 1000" electric vehicle demonstration project, plans to use about 4 years time, select the application of a number of demonstration city including pure electric vehicles, hybrid vehicles and fuel cell vehicles, 60000 units of clean energy vehicles. The promotion of "golden sun" project, plans to use 3 years in the demonstration part of the city to promote all kinds of photovoltaic technology and products. The total size of the demonstration project will be more than 600MW, the annual power generation will be more than 1 billion kWh. To promote the "ten city lights" project, has launched a pilot in the country's more than and 20 city, the promotion of LED (semiconductor) priority application in city public lighting, lighting and landscape lighting, is expected to reach 6 million in 3 years to promote the application of the scale of light.

Currently, the project has been in full swing. By the end of 2009, nearly 3 billion yuan of the first batch of central financial subsidies have been put in place.

Cao Jianlin said that the Ministry of science and technology is being developed in the 12th Five-Year plan, the new energy will continue to be the focus of development and priority areas of development. During 12th Five-Year, China will continue to increase efforts to support the development of new energy technology demonstration, and actively promote new energy grid generation, from the technical level to solve the problem of large-scale access to renewable energy grid. Increase investment in research and development of smart grid key technologies and equipment, will be carried out in a number of cities nationwide engineering demonstration. According to the actual requirements of Spratly Islands and Paracel Islands, we can develop the wind power, solar energy, energy storage and desalination as one of the living facilities and renewable energy power supply technology. To organize the implementation of the new rural energy plan, vigorously promote the comprehensive utilization of wind energy, solar energy and biomass energy in rural areas. The key technologies of advanced renewable energy such as heat energy and ocean energy are also studied.

Cost control rise of non material factors

Deputy director of the national energy board, deputy director of the new energy Shi Lishan pointed out that the current development of new energy industry, technology, knowledge and management issues and challenges, but also the practice of quick success. He explained that in the use of new energy and renewable energy in China, hydropower technology is relatively mature, but the existence of resettlement, lack of publicity and other issues. Wind power in the construction of large bases, the dominant pattern of wind farms, should also take into account the construction of small and medium wind farms and offshore wind power, the urgent need to solve the wind power grid operation of the outstanding contradictions. The problem of cost control of solar photovoltaic power generation. Factors affecting the cost of photovoltaic power generation projects, such as battery, silicon and other material factors, but also the installation, operation and other non material factors. Some of the construction cost of the project has exceeded the cost of materials. The utilization of biomass energy should be promoted in many fields such as electric power, transportation, heating and so on.

Not only concerned about the battery board, but also optimize the system, optimize the construction, otherwise it is difficult to reduce costs. "In order to control the cost of photovoltaic power generation, the history of Lishan emphasized through strengthening the construction and construction management, in order to increase the power generation cost control space.

According to reports, in 2006 the cost of solar photovoltaic power generation in China was 4 yuan, to 2009 has dropped to $1, while the original intended to achieve this goal for the time of 2015. At the same time, thin-film solar cell power generation costs have dropped to 1 yuan. Nevertheless, photovoltaic power generation is still higher than conventional energy costs, the need for a large number of subsidies, the future of its cost reduction is limited.

The application of finite to encourage demand side

Cao Jianlin said, in addition to R & D investment, cost control and other issues, new energy and renewable energy to the full range of application problems, namely how to infiltrate all aspects of life, change the form of life and production, is the new direction of energy utilization. "Solar energy and wind energy are thin energy sources (low density energy), which should be used more for domestic and domestic use. He said.

According to the Ministry of housing development of science and technology development center responsible person, the Ministry of Finance and
